To all whom t may concern Be it lmown that I, ROBERT W. RIORDAN, a'

'and Fig. 7

citizen of the United States, and a resident of the city of New York,borough of'Brooklyn, in the county of Kings and State of New York, haveinvented a new' and lmproved DustsSeparator, of which the folowing is afull, clear', and exact description.

This invention relates to a dust separator especially adapted for,although not necessarily limited to, vacuum cleaners.

AThe invention has for its general objects to improve the constructionand operation of apparatus of the character referred to so as to bereliable andeiiicient in use, comparatively'simple and inexpensive tomanufacture, and so designed as to permit of the easy and sanitaryseparation of dust from l su1table A more specific`object of theinvention is be placed in an` ordinary pail or bucket and submerged inWater, whereby the dust-laden air is caused to pass through the water bythe special construction of the device for the elimination' of thedustparticles from the air, the separator being so constructed that Ait canbe easil and quickly cleaned without the disagreea le features common todust bags or receptacles now 1n use, and since the dust is taken up bythe Water the mere emptying of the pail or the bucket disposes of thedirt.

With such objects in view, and others which will appearas thedescription proceeds, the invention comprises various novel features ofconstruction and arrangement of parts which will be set forth with parvFig. 6 is a modified form of dust se arator; 1s a perspective view o oneof the cylinders which go to make up thedust sep arator.

- Referring to the drawing, 1 desi nates the nozzle of a vacuum cleaner,2 the an, pump or other suction-producing device, and 3 the separator,the latter being arranged on the discharge side of the fan or pump, asshown in Fig. 1, or on the suction side', as shown in Fig. 2.

The separator is so designed that the dust is continuously separatedfrom" the air byv the dust-laden air being forced through a body ofwater, whereby the air escapes to the atmosphere and the particles arearrested by the water. The separator comprises -a pail 4 that containswa/ter 5 to-. a'

epth, and submerged in the Water 1s a separating device composed of aplus rality of nested cylinders 6 'concentrically arranged andsecuredtogether by a spider' 7, and over the cylinders is a disk or cover 8which-may be solid orl erforated.v The upper edges of they cylinv ershave spaced' ports 9 whereby air can freely pass out wardly. from thecentral cylinder successively to the outer one. The s ider or freine 7is fastened to the lower en of a pipe 10 which passes'through a hubv 11ina supporting frame 12, as shown in Figs. 3 and 4, or in a coveredplatel, as shown in Fig. 46. The position of the dust-separating de-Ivice in. the pail may be varied by sliding the pipe 10 up or down inthe hub 11, and when the desired position is attained the set-screw 14is tightened. The separating device can ticularity -in the followingdescription and i claims appended hereto.

In the accompanying drawing, which illustrates certain embodiments ofthe invention and wherein similar characters of reference indicatecorresponding parts in all the views, Figure 1 is a side view of avacuum cleaner and dust separator, the suction-producing device orblower being intermediate the vacuum nozzle and the dust separator; Fi2V is afsimilar view of a modification Ml'flnyvhich the separator isbetween the vacuum nozzle and the blower or suction-produc-- ing device;Fig. 3 1s an enlarged sectional view of the dust separator, the sectionbeing takenon the'line '3-3, Fig. 4; Fig. 4 is a lan view of the dustseparator; Fig. 5 is a orizontal section onthe line 55, Fig. .3;

against the cover to urge the latter downrest onthe bottom of the pail,and to insure propercirculation of the Water the bottom edge of theouter. cylinder has a notched flange 15, so that water can circulateunder 1t.

The disk or cover 8 is held seated by a spring 16 surrounding the pipe10, the upper end of the spring bearing against an abutment 17, and thelower end bearing -wardly.A This means of holding the cover yieldinglyclosed is advantageous, as it enables the cover to'be easily held inopen positionin case it is desired to run water into the cylinders froma faucet or nozzle in Washing out the lint that might collect on thecylinders. The frame 12 allows the top of the pail to be open so thatthe air can freely escape, as when the device is used `on the dischargeside of the suction-producing de- ,vice 2, as shown in Fig. l. When itis used on the suction side, as shown in Fig. 2, the cover 13 is clampedclosed in air-tight relation to the pail, as shown in Fig. 6. The cover13 also has an elbow 18 forcconnection with the suction-producingdevice. At thevtop of the pipe 10 is an elbow or other swiveled coupling19 to Which is connected the hose 20 through which the dust-laden air Y,passes to the separatorl LF rom the ioregoxng description taken inconnection with the accompanying drawing, the. advantages of theconstruction and method of operation will be readily understood by thoseskilled in the art to which the invention appertains, and While Ifhavedescribed the principle of operation, together-,With the device which Inovir consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative and that suchchanges maybe' made when desired as fall Within the scope of theappended claims;

Having thus described my invention, I

claim as new and desire to .secure by Letters Patent:
